Chapter 15: Echocardiography in mechanical circulatory support

Echocardiography is essential in identification of candidates for mechanical circulatory support (MCS) and provides key information for the management of critically ill patients with implanted assist devices.
Echocardiography is used for preoperative assessment, guidance during MCS device insertion, detection of complications, and guidance during weaning and explantation of the device.
Complications detectable by echocardiography, often associated with hemodynamic instability, include thrombosis, device malfunction, cannula displacement or malalignment, pulmonary embolism, aortic dissection, cardiac tamponade, and hypovolemia.
The nonphysiologic nature of the circulation in patients with MCS requires unique understanding and interrogation.
